SPECIFICATION forming part of Letters Patent No. 365,274, dated June 211887.

Application filed June 10, 1856. Svrial No. 204,?01. (No model.)

To all whom, it may concern.-

Be it known that l, BENJAMIN O. POLE, a citizen of the United States,residing at Camden, in the county of Camden, State of New Jersey, haveinvented certain new and useful Improvements in Car-Starters, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to 'carstarters and devices for operating them,being an improvement on Letters Patent of February 15, 1881, No.237,697; and the nature of this invention consists in certainconstructions of the various parts for the purpose of improvement tosaid patent and for the purpose of preventing the undue wear of parts,by which the load designed to be moved by the starter shall only beraised in the operation of starting, and not carried continuously by thering or wheels, all of which is more fully set forth in theanneXedspecification and claims.

Referring to the drawings accompanying this application, and formingpart thereof, Figure l is a sectional side elevation of my invention,showing the same in connection with the wheels ofa car. Fig. 2 is across-see tion of Fig. 1. Fig. 8 is across section of thecar-wheel,showing the differential ring,also in section. Fig. 4 is amodification of Fig. 3, wherein the ring is on the outside when a citypassenger-rail is used of T formation.

Referring to the drawings, upon the ordinary ear-wheel axle,A,is placeda split wheel, 13, which is free to revolve 011 the axle A. Between thewheel B and a similar wheel on the other side of the axle is a simpledivided sleeve, 0, bolted on the axle A, which is for the purposeofkeeping them apart and in their po sition close to the ordinarycar-wheel,D. This construction allows the split wheel B to freelyrevolve, and the sleeve 0 holdsin place wheel B, which would beotherwise forced in on the axle A when a side thrust came, like roundinga curve or turning a switch. The ring E is placed around the wheel B andcomes up in the groove at e. A space, e,permits the ring E to be free inits upward movement while rolling, but is confined in position laterallyby the flange b of the wheel At the top of the ring E is the operatingfriction-wheel G, through which the strain of the moving power-- horsesor motor-is transmitted to the periphcry of the ring E, and this ring E,moving forward, rolls up against the face I) of the wheel E and acts asa lever for starting the car, taking off so much weight as is requiredfor the traction of the ear. The wheel B, freely revolving on the axleA, comes to a stop when the ring-wheel E presses againstit,notwithstanding the ring E and the wheel D may bev in motion, and ateach impulse acts at once for the height of the leverage as a lever intraction, while not at all times sustaining the weight of the load andvehicle.

The prompter or wedge K is inserted between the free wheels B and thering E, and is of a form conforming to the inside radius of the ring Efor its outershape and the curve of the outside radius of the part c ofthe wheel B for its inner or upward shape. It may be of other shape.This prompter is more fully set forth in another application of mine,wherein it is claimed with wheels resting one within the other. Here itis in connection with a free wheel on the axle and an ordinary car-wheelcarrying the load, the'prompter or wedge acting when the ring E, whichis on the track, is operated by the operating-wheels G. The free wheelB, held in the position, as set forth, on the axle A, and forced or heldout against wheels D by sleeve 0, makes two freelyrnnning or loosewheels on axle A, and these wheels inside of two fixed wheels D on thesame axle-four wheels in alland in the event of turning switches andcurves where there is a central or inner riser provided, the free wheelsB will take the weight off of the wheels D, and in this manner theadvantages of free wheels will be derived at the curves and switches andplace where the risers are provided to make a contact with the wheel 13,making easy curving, and should wheels be thus added for curving andturning switches only,and not using the remainder of the start ingdevices, then the groove 6 may be dispensed with and the flange b fillup the therei 11- described groove-space.

The pedestal, as shown in Fig.11 of the Letters Patent before quoted,carries the guiderods H, which hold up the friction-wheels G and theconnecting-rod I to the singletree K, to the drawrod L, which isconnected to the moving power.

The frame of the ordinary ear is denoted by the letter M, and pedestaland its box by the letter N; the floor of the car by the letter O. Theprompter K will be inserted between the ring E. Y

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is I 1. In a car-starter, the ordinary car-wheel, D,provided with the free wheel B,ring E,and operating-wheel G,substantially as and for the purpose set forth.

2. In a car-starter, the wheel D, provided with wheel B, ring E,operating-wheel G, and

prompting device or wedge K, substantially as and for the purpose setforth.

3. In a car-starter, a car-axle provided with ordinary 'fixedcar-wheels, D, the additional free wheels, 13, and sleeve 0,substantially as specified.
